FPGA Explorer is an interactive platform designed to simplify the exploration and learning of Field-Programmable Gate Arrays (FPGAs). Whether you're a student, teacher, or hobbyist, this tool helps you understand, develop, and simulate FPGA logic in a visual and intuitive way.

👉 Try it online

You can use the file example.sdf to test the application.

You can also upload your own .sdf files to visualize and simulate them.

Features

• Visual Logic Simulation
  Simulate FPGA circuits in real time and watch how data flows through flip-flops, LUTs, and wires—perfect for exploring internal chip behavior.

• Educational Focus
  Designed for learning, FPGA Explorer makes it easy to understand digital logic by visualizing how components interact, step by step.

• Pivot Format
  Upload .sdf files and watch them automatically parsed into a structured JSON format designed for clarity and modularity.
  You can download the generated JSON, tweak it, and re-upload it to create your own examples effortlessly.

Manifest

• Functional Specifications
• Technical Specifications
• Test Plan
• User Manual
• Management Artifacts
• Source Code
• SDF Example
• JSON Creator

Prerequisites

• Node.js (v14 or later)
• npm (Node Package Manager)
• Python 3.x (for JSON Creator)

Configuration

1. Clone the repository

git clone https://github.com/algosup/2024-2025-project-4-web-fpga-team-4.git

2. Navigate to the directory

cd 2024-2025-project-4-web-fpga-team-4/src

3. Start the application

npm install
npm start

The interface will open in your browser at http://localhost:8080/code/client.html.

JSON Creator

FPGA Explorer includes a command-line script to help users generate custom .json files without writing them from scratch. This is ideal for testing small examples or building circuits manually.

⚠️ Note: This tool is optional and not the main feature of the platform.

Run the Script

/opt/homebrew/bin/python3 ./src/json_creator/json-creator.py

It will guide you step by step through:

• Adding LUTs, Flip-Flops, and I/Os
• Creating connections with timing delays
• Saving everything into a valid output.json file

You can upload the generated file directly into FPGA Explorer to simulate your custom circuit.

Important Notes

• Case sensitive: Use correct casing for element types (LUT, FlipFlop, IO)
• Unique IDs: Required for LUTs and Flip-Flops
• Valid timing: Must be a numeric value
• I/Os use names instead of numeric IDs
